insert into Phone values(‘vivo nex‘,3)

select * from Phone


create table User_X_Phone
(
	Id int primary key identity(1,1),
	PhoneId int,
	UserId varchar(64)
)


select * from Phone
select * from User_X_Phone

truncate table Phone
truncate table User_X_Phone
insert into Phone values(‘vivo nex‘,3)

create database Shop

CREATE TABLE Phone (

INSERT INTO `Phone` (`Id`, `Phone`, `PCount`) VALUES (NULL, ‘vivo nex‘, ‘3‘);

select * from Phone


create table User_X_Phone

	PhoneId int,
	UserId varchar(64)
